II. Imaging: Right ventricular dysfunction signs suggestive of increased right heart pressures

  1. Right ventricular dilation (RV diameter compared with LV)
  2. Right ventricular wall contractility
  3. McConnell's Sign
    1. Right ventricular tip contracts
    2. Right ventricular free wall does not contract
  4. Flattening of the septum in PSAX View

III. Differential diagnosis: Echocardiogram with right heart dysfunction

  1. Chronic Pulmonary Hypertension
    1. Right ventricle wall thickness >0.5 cm
  2. Cardiac Tamponade
  3. Right-sided Myocardial Infarction
